Log sources and channels
Exactly as MITRE states them in x_mitre_log_source_references. Where a channel is vague, it is vague in the source; kevmap does not tidy it.
| Log source | Channel | Data component |
|---|---|---|
| WinEventLog:Sysmon | EventCode=11 | DC0039 File Creation |
| WinEventLog:Sysmon | EventCode=1 | DC0032 Process Creation |
| WinEventLog:Security | EventCode=4624, 4648 | DC0067 Logon Session Creation |
Mutable elements
Parameters MITRE marks as environment-specific. These are the knobs you are expected to tune; they are why an analytic is not a rule.
| Field | Description |
|---|---|
FileNamePattern | Patterns like *.env, *credential* can be tuned to reduce noise or catch custom implementations |
ProcessAccessScope | Defines scope of access (e.g., only untrusted parent processes or high-risk processes) |
TimeWindow | Time delta between credential file access and use in logon attempt |
